JOHN C. TAYLOR, OF FINDLAY, OI-IIO, ASSIGNOR OF ONE-HALF TO ENOOI-IROSS, OF SAME PLACE.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 571,251, dated November10, 1896.

Application filed August 4, 1896. Serial No. 601 ,619. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN C. TAYLOR, of Findlay, in the county of Hancockand State of Ohio, have invented certain new and useful Improvements inCar-Couplings; and I do hereby declare the following to be a full,clear,and exact description of the invention, such as will enable othersskilled in the art to which it pertains to make and use it, referencebeing had to the accompanying drawings,which form part of thisspecification.

This invention pertains to car-couplings; and the object thereof is toprovide a coupler of the twin-jaw type with an improved j awlockingmechanism.

The invention consists in the novel features of construction hereinafterfully described and claimed, and illustrated by the accompanyingdrawings, in which- Figure 1 is a perspective view of the coupler shownin position upon a car. Fig. 2 is a vertical longitudinal sectional viewof the coupler. Fig. 3 is a sectional plan View. Fig. 4 is a .detailperspective View of the detent or look. Fig. 5 is a vertical sectionalview of the right-hand side of the draw-head,taken on line 5 5 of Fig.3.

A designates the draw-head, and B the pivoted jaw, the tailpiece O ofthe latter being provided upon its extremity with the rounded rib D.Traversing the rear portion of the coupler is pin E,and mounted thereonis the detent F, having in its rear portion the inclined slot G, wherebyit is adapted to travel forward and backward upon said pin. Upon theforward lower edge of detent F is roller H,which travels upon the bottomof the draw-head, thus reducing friction and making the detent extremelysensitive. With the detent in its forwardly-extended position it abutsagainst stop Lwhile its rear end rests and slides upon cleat J ,arrangedcentrally in the bottom of the rear portion of the coupler. Side flangesK and L upon the interior of the coupler guide the detent while beingadjusted, holding the same from lateral displacement. The front end ofthe detent is formed with depression M, into which the flange of the jawtakes when the coupler is automatically locking, thus facilitatiug andmaking more positive the operation.

The car may be provided with the crankshaft N or any other suitabledevice for operating chain 0, extending from the top of the detentupward through the draw-head and which when drawn upon serves to raiseand throw backward the detent upon pin E, so as to clear the extremityof tongue O of the jaw, and permit the same to swing outward to theposition indicated in Fig. 1.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. In a car-coupling, the combination of a di aw-head, ahorizontally-swinging jaw, a locking-block situated wholly within thedraw-head, the forward end of the block having a reciprocating movementon the bottom of the draw-head, the rear end of the block being cut awayand provided with an inclined slot extending horizontally therethrough,a pin extending transversely through the drawhead at a point above thebottom of the drawhead to permit the rear end of the lockingblock tomove downward as it moves forward within the said draw-head, and anoperating means extending through the draw-head thereinto andoperatively connected with the said block for moving it backward withinthe draw-head, substantially as shown and described.

2. The combination with the draw-head,the pivoted jaw, cleat J situatedin the rear portion of the draw-head, abutment I at the forward end ofthe draw-head and the detent slidable longitudinally in the draw-headand adapted to move upon the cleat and abut against the abutment,substantially as shown and described.

3. The combination of the draw-head, the pivoted jaw having its tailportion provided with flange D,the sliding detent providedwith adepression upon its forward end, Where it it is engaged by flange D asdescribed, substantially as set forth.

4:. The combination of the draw-head, the pivoted. jaw, the pivot-pin,the sliding detent having the inclined slot whereby it is adapted tomove back and forth upon the pin, the fricti0n-ro1ler carried by theforward end of the detent, and the side flanges or guides K and
